# 1.2 Non-Goals [Architecture documentation](README.md) > [1. Architecture Overview](1-architecture-overview.md) The architecture deliberately excludes: - Firmware boot, caller-defined ACPI and SMBIOS tables or device trees, PCI, vPCI, VMBus, and arbitrary devices. - SMT, multiple NUMA nodes, non-x86 guests, and nested virtualization. - General CPU or memory hotplug after readiness. - Restore across hypervisor backends or CPU generations, live migration, and capture-and-continue. - Scaling of the TSC, trapping of RDTSC, paravirtual clocks, and a virtual PMU. - Serialization of live network flows, native host handles, or the contents of a live host filesystem export. - Multi-container orchestration, including pod infrastructure, pause containers, dynamic root filesystem injection, and host calls that create additional containers. - Confidential computing, because the host is trusted with image content and guest memory. - Tenant authorization inside the VMM.
